- Application filed February 7, 1910.

Patented Nov. 15, 1910.

Serial No. 542,609.

To all whom it may concern:

Be it known-that I, DAVID RQLEVIN, a

citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Means for Removing Covers, of which the following is a specification.My invention relates to means for openmg or prying loose covers,particularly covers on blacking boxes and similar vessels, where it isnecessary to keep the cover on tight, either for the purpose ofpreventing the drying-out of the contents or the accidental loosening ofthe cover and spilling of the contents of the covered container.

The object of my invention is to provide a coyer-looseniilg device whichmay be applied to any can or tin box; which does not requlre riveting orpivoting in the box itself, which tends to interfere with the airtightjuncture of cover and vessel, and to make provision for certainty ofoperation.

I am aware that there are devices for this purpose, particularly a camarrangement riveted or pivoted to the box, and my invention is designedto overcome the deficiencies experienced in the prior constructions.

VVith the above-named general objects in view my invention consists inthe novel construction, combination and arrangement of parts.hereinafter described in detail, illustrated in the accompanyingdrawing, and incorporated in the appended claims.

Figure 1 is a perspective view of the opening device removed from thecan or blacking box. Fig. 2 is a perspective view of a conventionalblacking box made of tin. Fig. 3 is an edge view of the box with myinvention applied thereto. Fig. 4 is an enlarged fragmentof the box andopening device shown in section. Fig. 5 is a plan view of a fragment ofthe box and opening device. F 1g. 6 is aview similar to Fig. 4, butshowlng another section of the box.

In-the several views Q represents the can or blacking box provided witha cover 3 having an outturned flange 4. This cover is made to fittightly upon the can so as to prevent drying out of the contents. Thebox 2 is provided near its upper rim with a circumferential groove, beador depression 5 designed to receive a band 6 made of wire or othersuitable material. One end of this band or wire is bent at right anglesoutwardly to provide a radially projecting lug 7. The opposite end ofthe band or wire 6 is bent thrice at right angles to provide a pivotportion or bearing 8 which projects from the body of the can and ring 6parallel to the lug 7, and a hook 9 to engage. the lug 7 as shown inFig. 1, the hook being bent downwardly at right angles to the lug 7. Onthe pivot portion 8 is mounted a lever 10 which is stamped, preferablyout of a fiat piece of metal to provide a finger piece or hold 11projecting at right angles to the vertical side of the box when thedevice is mounted thereon, and an inwardly projecting spur 12. This spurnormally lies in the groove 5 underneath the outturned rim 4:.

For the sake of greater clearness of description or illustration thefinger piece 11 and lever 10 are shown arranged tangentially to thecircumference of the box, but these parts may also be curved so as tolie close to the box. The swing of the lever and its spur 19 beingparallel to the vertical side of the box, the spur will during itsmovement always be in close contact with said box and in engagement withthe rim 4. Hence, if desired, the rim need not be outturned but fiatagainst the box as usual. This form of construction permits theadjustment of the ring (3 of a given size to a box of smaller size bymaking the bend forming the hook 7 at the desired point on the ring orwire 6. The dotted lines in Fig. 3 indicate the manner in which thecover is pried off.

Having thus described my invention, I claim as new and desire to secureby Letters latent-- 1. The combination with a box provided with anannular recess in its outer circumference, of a wire bent into hook andpivot portions, said wire being located in said recess a finger-piece inthe form of a lever pivoted on said pivot portion to swing parallel tothe vertical side of the box, said lever having a spur to engage the rimof the box cover as set forth.

2. The combination with a box or can having an annular channel 5, of aband normally seated in, said channel and having hooks at its endsadapted to removably engage/each other to fasten the band in saidchannel, an outturned" pivot portion 8 on said band, the lever 10,provided wi.tl1 :1 my hand in the presence of hm subscribingfinger-piece 11 mounted to swing agamst the Witnesses. sides of the boxon said portion 8, and an inwardly projecting spur on said level" DAVIDLEVIN 5 adapted to engage the edge of the cover for Witnesses:
